here's a simple exercise, open your favorite media player. pull up its eq window. there should be some frequencies written there. set everything to flat, then play your fave tunes. raise one of the sliders so you can familiarize yourself with that frequency and what it boost. for example itunes/windows media, raise the slider at the far left 32Hz, that would be your low-mid. middle slider 500-1k for mids. far right slider 16khz for your highs. then try out all those in between.

Take into account that every single sub-range is covered by one octave. They are correlated to the 220Hz "A3" note where the lower midrange starts.
